Having read up on Dolby Atmos I have found out the following info.
Supported iPhones developer.dolby.com/platforms/apple/ios/device-support/
developer.dolby.com/platforms/apple/tvos/device-support/
it appears my Apple TV is $K and supports it, it was a freebie when I moved to Vodafone.
Others www.gizbot.com/mobile/features/list-of-smartphones-launched-with-dolby-atmos-sound-capability-065022.html
There may be more, it appears the higher newer mobile devices released since mid 2018 or early 2019 are likely to do so, but check before buying if that is what you want one for.
If you want to try Dolby Atmos from a computer there are some minimum requirements, and from what I understood on this page you need to connect to a Dolby Atmos enable receiver using HDMI from the computer to receiver. developer.dolby.com/platforms/html5/overview/
If you want to try it on you TV/Soundbar receiver have a read of this first see developer.dolby.com/blog/dolby-audio-over-hdmi-part-1-codecs/
"A SIDEBAR ON S/PDIF
S/PDIF (Sony/Philips Digital Interconnect Format) allows digital audio to be sent from a source device and a sink device over an optical or coaxial connection (by the way, I pronounce it SPEE-DIFF). It's historically been a popular connection type to get digital audio to soundbars as well as A/V receivers. S/PDIF supports 2-channels of uncompressed PCM audio OR Dolby Digital audio. S/PDIF does NOT support Dolby Digital Plus or Dolby TrueHD for 3 reasons. First, since there's no signaling on S/PDIF, there's no way for a source device to know whether a sink device supports newer audio codecs. Second, S/PDIF doesn't have enough bandwidth to support the worst case bitrates of Dolby Digital Plus or any bitrate for Dolby TrueHD (greater than 6000 kbps). Lastly, content protection rules (e.g. HDCP) don't allow for newer formats to be sent over unencrypted links like S/PDIF."
I saw reported that Tidal supports it tidal.com/partners/dolbyatmos you can get a free trial here, also Amazon HD does, but you will need a device that is capable of recognising and playing it, for example :-

My MacBook even though quite old has an HDMI port and runs the most recent MacOS so reading through the requirements it should support Dolby Atmos through a set off Headphones or using HDMI to a Dolby Atmos sounder or receiver. My Yamaha YAS207 has DTS:X decoding but does not support Dolby Atmos. So I cannot try it on that.
The cheapest Dolby Atmos receiver I can find is from Marantz at around £699 the rest seem to be over £1K, and the cheapest sound bars that supports Atmos are form LG and Sony at £299.
Someone inferred earlier that Dolby Atmos worked with standard stereo recordings and had some effect on them, as far as I can find this is is not the case, for Dolby Atmos processing to have any effect it has to be recorded using the Dolby Atmos system.
On the experimental from it seems people are trying this www.cnx-software.com/2019/06/26/raspberry-pi-4-4k-video-playback-libreelec/
